Dentures have been a reliable way to replace missing teeth for generations, and they still work well for many people. But every denture eventually gets loose, every denture eventually needs a repair or a reline, and many patients reach a point where they want something more stable. At Dentist Pymble, we look after dentures for patients across the Ku-ring-gai region, and the conversations we have are usually about the right way to fix the problem rather than putting up with it. This page covers the most common denture issues, what can be done about them, and the implant-supported options that have changed what is possible.

Why do dentures become loose?

The single biggest reason is bone resorption under the denture. Once the natural teeth are gone, the bone that used to support them begins to shrink, slowly and steadily, for the rest of the patient’s life. As the ridge flattens, the denture that once sat snugly on it starts to move, slip, and rock. This is why most dentures need a reline or replacement every 5-7 years — the fit changes as the ridge changes.

Other reasons include weight loss or gain that changes the soft tissue under the denture, generalised ageing of the oral tissues, a denture that was never quite right to begin with, and changes in the bite from wear on the artificial teeth. The good news: a loose denture is almost always fixable, and the fix is usually straightforward.

What are my options for loose dentures?

The cheapest and fastest fix is a reline — a new layer of material added to the fitting surface of the denture to take up the slack left by the resorbed ridge. A reline is usually done in a day and gives the denture a new lease on life. The next step up is a new denture, made from scratch to the current shape of the ridge. This is the right answer if the existing denture is old, worn, or no longer aesthetically acceptable.

The most stable fix is an implant-supported overdenture — a removable denture that clips onto 2-4 dental implants placed into the jaw via Locator attachments or a small bar. The denture still comes out for cleaning, but it clicks firmly into place and does not move during eating or speaking. For many patients, this is the closest they will get to a fixed solution without going to a full arch of implants.

Can broken dentures be repaired the same day?

Often, yes. If the denture has a clean break, a tooth has come off, or a clasp has bent, our dentures service at the Pymble practice can usually send it to the lab and have it back the same day or the next morning. The key is to bring all the broken pieces, and to resist the temptation to glue it yourself — most household glues do not hold up in the mouth and can damage the denture acrylic in a way that makes a proper repair harder.

If the denture has shattered, the framework is bent, or the teeth are significantly worn, a repair may not be the right answer. In those cases, we will talk you through whether a new denture is the more sensible long-term option.

Denture reline vs new denture

A reline adds a new layer of material to the fitting surface of the existing denture. It is faster, cheaper, and gives you back the fit of a new denture using the teeth, acrylic, and framework you already have. It is the right answer when the denture is in good condition but the ridge has changed. A reline is usually soft (more comfortable for tender gums, but less durable) or hard (more durable, but less forgiving of pressure spots).

A new denture is the right answer when the existing one is old, the teeth are worn, the bite has changed, or the aesthetic is no longer acceptable. It is a bigger investment but starts from scratch and gives you full control over the look, the fit, and the bite. We will always be straight with you about which one is the better answer for your specific denture.

Implant-supported dentures — are they worth it?

For many patients, yes. An implant-supported overdenture is the most significant upgrade in denture comfort available, and it is particularly useful for the lower denture, which is notoriously hard to keep stable with suction alone. Two to four implants per arch, with Locator attachments or a bar, give the denture something to clip onto. It still comes out for cleaning, but it does not move during eating or speaking, and the chewing efficiency is dramatically better.

The trade-offs are cost (the implants are an additional investment on top of the denture), the surgery itself, and the 3-6 month healing period before the denture can be attached to the implants. For many patients, the trade is well worth it. We will always lay out the options, the costs, and the timeframes, and we will not push you toward implants if a reline or a new conventional denture is the right answer for your situation.

How much do denture repairs cost in Pymble?

It depends on what is needed. A same-day reline is at the lower end. A repair with a new tooth or a rebent clasp is in the middle. A new denture or an implant-supported overdenture is at the top. We will always provide a written quote after the assessment, run a health-fund check on the day, and talk through the item numbers from the Australian Dental Association schedule so you know exactly what you are paying for.

How do I prevent denture problems?

The biggest one is regular review. We like to see denture patients once a year for a check-up, a reline assessment, and an oral cancer screen (denture wearers are not immune to oral cancer, and the soft tissues under a denture should be checked regularly). Clean your denture daily with a soft brush and a denture cleaner (not regular toothpaste, which is too abrasive), take it out at night to let the tissues rest, and call us if you develop any sore spots, looseness, or a change in the bite.

If you live in Pymble, Gordon, Turramurra, Wahroonga or anywhere else in the Ku-ring-gai area and you have a denture that is not working the way it should, call our practice. We see neighbouring Gordon patients and other nearby residents, and we will be straight with you about what is worth fixing and what is worth replacing.

Frequently asked questions

How long do dentures last? With proper care and regular relines, a well-made denture can last 5-10 years. The teeth on the denture wear down over time, the fit changes as the ridge resorbs, and most patients need either a reline or a replacement within 5-7 years.

Can I sleep in my denture? It is generally better to take it out at night to let the tissues rest and to reduce the risk of fungal infection (denture stomatitis). If you do sleep in it, take it out for at least a few hours during the day to give the gums a break.

Will I need adhesive? A well-fitting denture should not need adhesive. If you find yourself relying on adhesive to keep the denture in place, it usually means the denture needs a reline or a replacement. We are happy to assess the fit and talk through the options.

Is a soft reline better than a hard reline? Soft relines are more comfortable for tender gums but less durable and need to be replaced more often. Hard relines are more durable and longer-lasting but can be less forgiving of pressure spots. The right answer depends on the condition of your gums and the denture.

How do I clean a denture? Brush it daily with a soft denture brush and a denture cleaning paste (not regular toothpaste, which is too abrasive). Soak it in a denture cleaning solution overnight. Rinse thoroughly before putting it back in your mouth.
